Bracket families

4 clusters across 5 contracts.

These contracts were grouped by title similarity. The headline aggregate combines all clusters; verify the cluster you actually need before quoting a number.

Heads-up — heterogeneous clusters

The top two clusters share only 15% of their title tokens — “Will CPI rise more than” vs “Will year-over-year Core CPI inflation for 2026 fall below 2.2%”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

The core CPI month-over-month increase for May 2026 is most likely centered around 0.2%, with prediction markets placing a 63% probability on that outcome. Expectations remain subdued for significant spikes, as there is a only a 4% chance for a 0.4% increase and a marginal 1% chance for a 0.5% increase.

  • Most likely 0.2% MoM core CPI
  • Tail risk of 0.4%+ remains low
  • Current 0.2% market-implied peak
  • Core inflation stabilization

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
